Star Amber Riley covered Houston's biggest hit, "I Will Always Love You," for the FOX musical's Valentine's Day episode, in which her character, Mercedes, says goodbye to both her current boyfriend Shane and ex-beau, Sam.

Riley's rousing cover was written and planned by Glee's team long before Houston's death, but producers of the show dedicated the episode to Houston by adding a final title card at the end credits: "Whitney Houston 1963-2012. We will always love you."

It's the second high-profile tribute to Houston and her trademark song in the past few days; Jennifer Hudson sang it during the "In Memoriam" tribute at Sunday's Grammy Awards.
